Abstract: 【Abstract】Objective To investigate the effect of IV3000 dressing on the prevention of early catheter-related infection in peritoneal dialysis (PD) patients. Methods A total of 43 patients with peritoneal dialysis catheters were randomly divided into experimental group or control group. The experimental group used IV3000 dressing for catheter outlet nursing, and the control group used 3L wound dressing. The exit site score, catheter-related infection, skin abnormalities, comfort degree of the patients, dressing integrity, dressing exchange frequency, and expense of the dressing were compared after the treatment for 6 weeks between the two groups. Results Compared with the control group, the experimental group had lower exit site score (Z=-4.644, P<0.001), lower catheter-related infection rate (x2=8.419, P=0.016), lower skin abnormality rate (x2=23.872, P＜0.001), less dressing exchange frequency (t=-16.321, P＜0.001), better comfort degree of the patients (x2=14.614, P＜0.001) and higher dressing integrity (x2=21.428, P＜0.001). The expense of the dressing was similar between the two groups (t=-1.453, P=0.154). Conclusion IV3000 dressing used in the early nursing of peritoneal dialysis catheter outlet had a better effect on the prevention of catheter-related infection and unplanned dressing exchange. IV3000 dressing was relatively comfortable and safe, and can be widely used clinically.
